Added ability to forward refs in Bar and Path components

[Cperez2187]

This will allow the user to pass in a ref to the <Bar /> component when using the custom dataComponent prop for <VictoryBar />. This will allow users to set individual refs for each bar in their data set as well if they use a ref map and ref callback, allowing for better accessibility options.

See "Focus With Refs" story under VictoryBar stories when running Storybook

ex.

const GetThemBars = (props) => {
...
const itemsRef = useRef(null);

  const getMap = () => {
    if (!itemsRef.current) {
      // Initialize the Map on first usage.
      itemsRef.current = new Map();
    }
    return itemsRef.current;
  };

  const focusOnBar = (id) => {
    const map = getMap();
    const node = map.get(id);
    node.focus();
  };
  
  return (
  <VictoryBar
  ...
  // add event handler to call focusOnBar()
  dataComponent={
    <Bar
      tabIndex={0}
      ref={(node) => {
        const map = getMap();
        if (node) {
          map.set(node.attributes.index.value, node);
        } else {
          map.delete(node.attributes.index.value);
        }
      }}
    />
  }
  />
  )
  ...
}
